TEPCO To Use New Floating Robot To Inspect Unit 1

TEPCO and Hitachi are working on a floating robot to inspect the torus area of the damaged reactors. The new robot looks like a boat and carries a number of sensors and cameras to facilitate inspecting the inner area of the torus room. It has been suspected that the area where the containment structure meets the downcomer pipes for the torus is a potential break through location for melted fuel.
